Insteon dimmer or keypad long press / press and hold for dimming

Hi! I’m relatively new to Home Assistant and currently evaluating the setup for a home remodel. In search for good keypads to control multiple lights I keep coming back to Insteon keypads (have a few currently). I tested the integration in HA and it works quite well.

What I can’t figure out: Is it possible to detect press and hold / long press on a keypad button to adjust a dimmer via HA? I’m going to have some regular loads but most will be LEDs controlled by Shellys or similar so direct control from Insteon to Insteon is not an option

I looked through the code and only found button press or switch on / off events, no long press. Is there something I’m missing or is it really not possible?
